The amount of these comments I see is absurd. These comments sole purpose is to get an upvote and is not engaging in anyway. That's not what steemit is supposed to be about. I also often see comments asking for upvotes, and that is definitely not the way to go about it.
All the comment types you listed are most likely spam if you check their comment history - and could potentially be flagged. I suppose they might eventually learn what works and what doesn't.
I wouldn't be surprised to see some pop up here specifically because they didn't even bother to read your post. If only they would read it.. you gave them good advice:
"Instead of putting "little effort" into faking it, put "little effort" into enjoying, learning and opening your mind to others' minds, then comment.
Your upvotes will come as you are wanting them to at that point and a following will begin."
Yes, this will be fun to watch for... Especially if a whale comes buy and gives it an upvote. Seems the bigger the upvote, the more of these show up.
